-// The `Status` type defines a logical error model that is suitable for different
-// programming environments, including REST APIs and RPC APIs. It is used by
-// [gRPC](https://github.com/grpc). The error model is designed to be:
-//
-// - Simple to use and understand for most users
-// - Flexible enough to meet unexpected needs
-//
-// # Overview
-//
-// The `Status` message contains three pieces of data: error code, error message,
-// and error details. The error code should be an enum value of
-// [google.rpc.Code][google.rpc.Code], but it may accept additional error codes if needed.  The
-// error message should be a developer-facing English message that helps
-// developers *understand* and *resolve* the error. If a localized user-facing
-// error message is needed, put the localized message in the error details or
-// localize it in the client. The optional error details may contain arbitrary
-// information about the error. There is a predefined set of error detail types
-// in the package `google.rpc` which can be used for common error conditions.
-//
-// # Language mapping
-//
-// The `Status` message is the logical representation of the error model, but it
-// is not necessarily the actual wire format. When the `Status` message is
-// exposed in different client libraries and different wire protocols, it can be
-// mapped differently. For example, it will likely be mapped to some exceptions
-// in Java, but more likely mapped to some error codes in C.
-//
-// # Other uses
-//
-// The error model and the `Status` message can be used in a variety of
-// environments, either with or without APIs, to provide a
-// consistent developer experience across different environments.
+// See https://cloud.google.com/apis/design/errors.
 //
-// Example uses of this error model include:
-//
-// - Partial errors. If a service needs to return partial errors to the client,
-//     it may embed the `Status` in the normal response to indicate the partial
-//     errors.
-//
-// - Workflow errors. A typical workflow has multiple steps. Each step may
-//     have a `Status` message for error reporting purpose.
-//
-// - Batch operations. If a client uses batch request and batch response, the
-//     `Status` message should be used directly inside batch response, one for
-//     each error sub-response.
-//
-// - Asynchronous operations. If an API call embeds asynchronous operation
-//     results in its response, the status of those operations should be
-//     represented directly using the `Status` message.
-//
-// - Logging. If some API errors are stored in logs, the message `Status` could
-//     be used directly after any stripping needed for security/privacy reasons.
+// This struct must remain binary-compatible with
+// https://github.com/googleapis/googleapis/blob/master/google/rpc/status.proto.
